Crystal structure and thermal behaviour of copper(II) and zinc(II) complexes with <i>N</i> -pyrrolidine- <i>N</i> ′-(2-chloro-benzoyl)thiourea

Abstract

The crystal structures and thermal behaviour of bis(N-pyrrolidine-N′-(2-chloro-benzoyl)thioureato)zinc(II) (ZnL2) and its copper(II) analogue (CuL2) are reported. In both structures, the metal atoms are coordinated by two oxygen and two sulfur atoms to form neutral trans-square planar (Cu) and distorted tetrahedral (Zn) species. The thermal decomposition of the complexes was investigated by TG and DTA.
